probably not. aside from things like there probably being differences in the control registers, i don't believe that the butterfly has a line connected to DTR for autoreset.

Yep it has a level converter to deal with a normal RS232 from a pc.
However I have an ftdi usb/serial converter and I'm planning to modify the avr butterfly to connect it directly, bypassing the level converter. And I'll connect DTR and RTS to reset too as it's in the arduino duemilanove.

Apart from that isn't possible to add avr butterfly support to adaboot? I noticed in the code an #elif defined __AVR_ATmega169__ so this µC is already considered in the code, so mabe wouldn't be too difficult to adapt adaboot for the butterfly, at least I hope...
